Lamp shade mounting means



July 4, 1939. P. cHlLo LAMP SHADE MoUNTING MEANS Filed March l2, 1958 Patented July 4, 1939 UNITED STATES PATENT OFFICE 8 Claims.

My invention relates to lamps equipped with shade supporting iixtures in the form of a harp wherein the shades may be rocked or tilted on their supports.

One of the objects of my invention is to provide a device of but few parts, inexpensiveto construct and assemble and which will function in combination to hold the shade positively in any desired tilted position on its support against the vibrations or jars to which lamps are frequently subjected when in use.

It is another object of my invention to provide a construction so arranged that the supporting harp may be completely formed or made and the shade holding means thereafter be easily assembled and installed thereon.

My invention preferably contemplates a supporting harp having a top cross bar and side arms depending therefrom and it is a further object of my invention to provide a shade mounting or holding means of spring material having a central plate portion swingably mounted on the cross bar and arms adapted to bear with considerable spring pressure against the respective arms of the supporting harp, there being on one of the arms a series of depressions in any one of which the coengaging arm may be dispo-sed thereby positively locking the shade holding means at the desired angle with respect to the supporting harp.

The invention consists of the novel constructions, arrangements and devices to be hereinafter described and claimed for carrying out the above stated objects and such other objects as will appear from the following description of a preferred embodiment of the invention illustrated in the accompanying drawing, wherein:

Fig. 1 is an elevational View of a lamp equipped with shade supporting means embodying the principles of my invention;

Fig. 2 is a side elevational View on an enlarged scale of the shade holding means;

Fig. 3 is a plan `view of Vthe parts shown in Fig. 2; Y y

Fig. 4 is a sectional View taken on the line 1 4 of Fig. 3; and

. Fig. 5 is a sectional view taken'on the line 5 5 of Fig. 3. f

Like characters of reference designate like parts in the several views.

The lamp I0 is provided with a shade support II which is generally in the form of a harp, the electric lamp bulb I2 being positioned within the harp and screwed into the lamp socket in the usual manner.

The supporting harp at its upper end is pro-r vided with a cross bar IIa and side arms IIb as best shown in Fig. 4.

The shade holding means comprises a central plate I3, and integrally formed therewith are 5' arms I4. The parts I3 and I4 are formed to provide a slot I5 adapted to receive the cross arm IIa of the supporting harp. A disc I6 is positioned over the plate I3, the two parts being secured together with the cross arm therebe- 1 tween by turning over the edge portion I6a of the disc I5. A mounting element in the form of a threaded stud I1 is provided with a collar I8 adapted to bear against the upper face of the disc I6, the lower end of the stud extending l" through an opening I6b in the disc I6 and then being riveted over or upset at IIa against the under side of the disc to secure the parts together.

A shade I9 is carried on a frame comprising a collar 20 and arms 2|, the collar 20 being zo adapted to i'lt snugly around the collar I8 of the mounting stud I'I. The shade is locked in position with the collar 20 bearing on the disc I6 by means of a nut or flnial 22 threaded on the stud I'I against the collar 20 as clearly shown 25 in Fig. 4.

It will now be apparent that the shade mounting means may be readily rocked on the cross bar IIa of the supporting harp. The means provided for locking the shade in the desired 30 tilting position will now be described. In the embodiment illustrated, the arms I4 are in the form of segments as clearly shown in Fig. 2 and are provided with a series of depressions 23. The spring arms I 4 if unrestrained are spaced 35 much farther apart than the distance between the rigid arms IIb and the arms I 4, therefore, bear with considerable spring pressure against the inner sides of the respective arms IIb of the supporting harp, said arms IIb being adapted 40 to rest in any one of the adjacent depressions 23. In order to limit the extent to which the shade may be tilted, stops 24 are provided on the extreme ends of the segmental arms I4. The relation between the stops 24 and the depres- 45 sions 23 with respect to the adjacent arms IIb is clearly shown in Fig. 4.

It will be. apparent that the shade holding means described is well adapted for its purpose. 'Ihe parts are inexpensive to construct and can 50 be readily assembled assembled and mounted on the harp support after the latter has been completely formed which facilitates factory production since the harp supports may be formed independently of the shade mounting means. The 55 spring arms I4 bear securely against the arms Hb of the harp support and in use effectively hold the shade tilted at the desired angle notwithstanding jars and vibration to which lamps are generally subjected.

I do not intend to limit the invention to the details of construction shown and described, except only in so far as certain of the appended claims are specifically so limited, as it will be obvious that modifications may be made without departing from the principles of the invention.

I claim:

1. In a shade support for lamps, the combination of supporting means including a cross bar and an arm at each end thereof, holding means of spring material swingably mounted on said cross bar between said arms and having arms initially spaced farther apart than the rst named arms and adapted to coengage with said rst named arms, said holding means including a plate portion provided with a slot in which said cross bar is disposed, and a shade mounting plate disposed over said cross bar and having its edges turned against the bottom of said plate portion.

2. In a shade support for lamps; the combination of an upstanding supporting frame including a top cross bar portion and side arms extending downwardly therefrom; holding means swingably mounted on said cross bar portion and including a downwardly extending arm; means for holding said last named arm in rm Contact with one of said rst named arms; and a shade mounted on said holding means and extending downwardly and around said cross bar portion, holding means, and arms; one of said contacting arms having a series of depressions for receiving the other of the contacting arms and for maintaining the shade in the desired adjusted position.

3.
